Nowadays protecting data communications becomes more and more important. The embedded TCP/IP stack of Cinterion® wireless modules supports server and client authentication for Transport Layer Security (TLS) for all services except Listener services.

The concept of TLS for Cinterion® wireless modules is targeted on industrial applications capable of secure communication. The Cinterion® wireless module acts as TLS/SSL client and supports server and optionally client authentication.

The attached slides guide you through the TLS certificate loading process on the EXSx2 module (CATM/NB/2G).
